Georgia and Alabama, rare. Black, uniformily covered with ashy hair, and 

 with scattered short suberect bristles. Head and thorax confluently punctured, 

 channeled : the latter one third longer than wide, rounded on the sides before 

 the middle, very slightly narrowed behind; anterior constriction moderately 

 distinct ; elytra one half wider than the thorax, coarsely and densely punctured, 

 variegated with small spots of more dense ashy pubescence. 



Although Prof. Haldeman's description is long anterior to the date at which 

 the present genus was established, he unfortunately did not give any generic 

 character, and I was therefore compelled to change the name given by him.

South Carolina, Dr. Zimmerman : the detailed description of La Ferte leaves 

 nothing to be added : from the following species it is easily distinguished by its 

 narrower form and canaliculate thorax. 



2. S. b a d i i p e n n i s , fuscus subtiliter dense cinereo-pubescens, capite tho- 

 raceque nigris hoc campanulato, latitudine fere breviore, elytris badio-testaceis,

 tion short, distinct only at the sides : elytra wider than the thorax, coarsely 

 punctured, the punctures smaller towards the tip; light yellowish brown. Feet 

 reddish yellow : first joint of the antennae brown.

Two specimens found at Fort Laramie, in Nebraska territory. Black, slightly 

 bronzed, finely pubescent : head and thorax confluently punctured, the latter not

 to the base, finely canaliculate, with a slight impression each side at the middle : 

 anterior constriction short, deep. Elytra densely and coarsely punctured, one 

 half wider than the thorax, variegated with numerous small round spots of 

 dense whitish hair. 



Although colored like the species of the preceding genus, the palpi terminate 

 in a long cultiform joint.
